[0035] Example: such as figure 1 Shown is a flange forging process disclosed in the present invention, step S1: cutting, using a band saw to cut a long blank with a square cross section, and cut it into multiple billets. The weight of each billet is 1.05 to 1.10 times the weight of the qualified flange. The required weight can be converted into the required volume of the billet through the relational formula of density, mass and volume, and then the length of the required billet can be calculated through the cross-sectional area of the billet, and the required billet can be cut according to the length. Quality billets.
[0036] Step S2: heating, placing the billet in a natural gas furnace for heating, the temperature of the natural gas heating furnace is 1180°C~1220°C, so that the temperature of the billet is higher than the recrystallization temperature and lower than the solidus temperature.
[0037] Step S3: making a circle, the billet is placed on the circle making mol...
